Abstract: APPARATUS AND METHOD FOR RECORDING        AND REPRODUCING DIGITAL-DATA        Abstract of the Disclosure The present invention relates to an apparatus for detecting digital signals played back from a magnetic tape wherein a signal information is recorded in the form of magnetic flux reversals.  The magnetic flux reversals, during playback, produce a varying signal which has a peak amplitude.         The improvement in the apparatus is comprised of an amplifier for amplifying varying signals.  The amplifier has a first input receiving the varying signals and a second input.  The second input provides an amplified output inverted with respect to the amplified output created by the first input.          A coupler is provided which is responsive to a predetermined level of the output signal for coupling the output signal to the second input.  A storage unit is provided, coupled to the second input whereby the output signal follows the varying signal at the first input until the coupler conducts thereby maintaining the output signal constant and in response to a slope reversal of the varying signal.  The input signals to the amplifier become additive producing an abrupt reversal in the polarity of the output voltage from the amplifier.

Abstract: MULTIZONE AIR TERMINAL     ABSTRACT OF THE DISCLOSURE         The invention provides an air terminal capable of serving multiple zones with either variable volume, constant temperature air or variable temperature,  constaant volume air, or both, without any reheating of cold air.  The terminal consists of a cold air plenum and a return air plenum.  The cold air plenum is served with cold air from a primary cold duct.  The air is introduced into this plenum through a damper which is controlled by a regulator for maintaining a constant pressure in the cold air plenum.  The return air plenum is supplied with return air by a constant pressure recirculating fan mounted in the terminal.          Constant volume  variable temperature air is supplied to the zones through thermostatically controlled mixing dampers which mix air from the cold plenum with air from the return plenum.   A heating unit downstream from the mixing dampers selectively raises the temperature of the air provided to a zone.  The heating is controlled in sequence with the mixing operation so that only return air can be heated.  Constant temperature variable volume air supply is provided from the central terminal to serve zones that neither require heat or zones with controlled heat available from another source.  In another embodiment, a hot air plenum is installed in fluid communication with the air in the return air plenum.  A mixing damper mixes return air and hot air when the cold air dampers are completely closed off to provide heating to a particular zone.

Subsequent objects launched by the launching member are launched then toward the first of the objects already captured by the magnetic target member.  It being the object of the game to capture all of the objects in a straight line and not have the objects grouped around or branched to be captured.

Abstract: IONTOPHORETIC TREATMENT APPARATUS                        ABSTRACT       This invention relates to a device for conven-iently effecting iontophoretic treatment of the surface of the human body.  Prior art devices for the iontophor-etic treatment of parts of the body such as the hands or feet have the undesirable effect of causing the treatment current to flow through parts of the body not being treated.  Further, iontophoretic treatment devices known heretofore have been cumbersome and awkward to use, and could only be used by trained medical personnel who had to supervise the administration of the treatment of a patient.  The present invention overcomes these defi-ciencies by providing a self-contained iontophoretic treatment apparatus which includes a support structure on which is mounted a pair of electrodes in generally close proximity to one another as well as a source of electrical power and appropriate controls for delivering electrical power to the electrodes.  me electrodes are arranged so that, for example, the palm of a single human hand can be placed on the device and simultaneously contact both electrodes, thereby confining the ionto-phonetic treatment to the palm surface of the hand. Alternative embodiments of the invention specially adapted for treating the plantar surfaces of the feet and the axillae are also disclosed.

Abstract: MULTIPLEXER SYSTEM PROVIDING IMPROVED BIT COUNT INTEGRITY                        Abstract A multiplexer system providing a transmission frame field containing information derived from the cumulative total of stuff bits used over a plurality of frames.  The stuff bits which also have assigned positions in the transmission frame are generally used in asynchronous systems to compensate for the input data rate of a group not being a fixed submultiple of the transmission rate.  The demultiplexer system uses the information derived from the cumulative total to improve the bit count integrity performance of data channeled out to a user device.  Also, during transmission fade conditions, the demultiplexer uses information derived from the frequency of past stuff operations to maintain group bit count close to its expected value.

Abstract: 12.                       Abstract The present system and apparatus for pumping an oil well dumps out the stretch and over travel in sucker rod over travel particularly when the rod string approaches its point of reversal of direction either up or down.  This is accomplished by decelerating the rate of travel of the rod string and at its end of travel pausing for a time period sufficient to allow rod string oscillations to damp out prior to reversal of rod string direction which due to the long length of the rod string, its weight and the weight of the trapped oil avoids breaking the rod string and the time loss occasioned thereby in both loss of well production and costly replacement of equipment and the time loss resulting therefrom.          The present invention also achieves substantial recovery of hi-viscosity oil not recoverable at present by standard recovery procedures.  This is accomplished with a sensor positioned to be actuated by the ram of the hydraulic drive.  When the sensor is actuated, it energizes a time delay relay which holds the sucker rod string in the upper most raised position allowing the suction to be maintained on the bottom hole pump with the standing valve open.  This allows the hi-viscus oil to enter the bottom hole pump barrel.  When the time delay relay is released, the sucker rod string starts its downward movement closing the bottom hole standing valve.  This traps the hi-viscus oil in the pump barrel which is then displaced by the downward movement of the plunger in the bottom hole pump.

Abstract: Abstract of the disclosure The invention relates to a method for controlling a piston fed wood grinder.  In order to achieve a uniform quality of the pulp the rate of  feed movement of each piston is controlled to an essentially constant value by direct digital measurement of the actual rate of feed movement, by comparing the actual value to a preset value and by compensating  differences therebetween. Variations in  the piston feed pressure and in  the grinding power are preferably taken into account by means of additional signals related to these factors and added to or subtracted from the sig-nal representing the  actual value of the rate of piston feed movement, depending on the situation.
